Inorganic ion exchange materials

The preparation, composition, structure and leaching characteristics of a crystalline, ceramic radioactive waste form have been discussed, and where applicable, compared with vitrified waste forms. The inorganic ion exchange materials used such as sodium titanate were prepared from the corresponding metal alkoxide. The alkoxides were reacted in methanol with a base containing the desired exchangeable cation and the final powder form was produced by hydrolysis in an acetone-water mixture followed by vacuum drying the precipitate at ambient temperature.

Figure 7 Correlation between the parameter (Z/r ) and valency of central metal. Values of r are taken from Ref 115, assuming that the metals have a coordination number (CN) of 6 ( ) except Li, Be, Si, and Mn which have CN4 (4). (From M.

The major objective of this chapter has been to demonstrate the utility of concepts that derive from the interpretation of the selectivities of inorganic ion-exchange materials. It should be realized that even in the simplest cases understanding of the hictors and mechanisms underlying ion-...

The properties of a- or y- zirconium hydrogen phosphate, a synthetic inorganic ion-exchanger material with layered structure, as "heterogenizing" support for carbonylation reactions are still to be studied. Our first studies in this field showed that the Pd(II)-2,2 -bipyridyl complex intercalated in these materials catalyzes the oxidative carbonylation of aniline even though its activity falls with time, because the support slowly loses palladium and deactivates during the catalysis process [2].
